somebody presented me a complete '86 3.5L M30 … and i'm interested to have a spare for eventually my 01/70 blue coupe who has still his '69 2.8L engine with famous head …. i could overhaul that engine and have time... engine is already 5 years out of "a" car …. for a project that never came. It has the manual flywheel . but what is the average value for such engine ? when you ask sellers they ALL have low mileage and come from a rear ended wreck…. Can we check something visual on seller's site ? and i do not mean compression test etc.... because i would at least soak the pistons with diesel before ever turning it . Injection /ECU /manifold is there but not important for me , as i would run it with webers.....even delete the distributor as we use a dedicated ignition module with coilpack. We just need the crankshaft sensor.
